Galilean Genesis: an alternative to inflation
Speaker(s): Paolo Creminelli
Abstract: I will discuss an alternative to inflation based on a Galileon field. The model starts in a (contracting or expanding) quasi Minkowski phase and all the energy of the Universe in generated suddenly in a sort of Genesis associated with a strong violation of the Null Energy Condition. The symmetries o... read more

The effective theory of quintessence: the w<-1 side unveiled
Speaker(s): Paolo Creminelli
Abstract: We study generic single-field dark energy models, by a parametrization of the most general theory of their perturbations around a given background, including higher derivative terms. In appropriate limits this approach reproduces standard quintessence, k-essence and ghost condensation. We find no ge... read more
